Should I do it or should I not?
Anyone got any idea on the performance hit?

Cheers

 

 

 

 

 

That BIOS only fixes the Managment Engine vulnerabilities with no performance issues.

 

Kernal Memory will require another BIOS and OS patch, and will have some slowdowns.

Updated my Windows 7 dev VM today with latest security patches... And this happened:

 

 

Remember, as per above "Windows 7 and Windows 8 have more user-kernel transitions because of legacy design decisions, such as all font rendering taking place in the kernel."

 

Damn.

 

 

Anecdotally my main desktop PC (Windows 10) has had the OS patch, and its crashed twice since, when I cant remember the last time it ever crashed before the patch.

 

I cant blame the patch for certain, and its been very hot in the middle of summer here right now.

I have been told by @freitasm  that this is not the fix for the Intel Kernel Memory Vulnerability this update is for something different.

How is this not already a class action lawsuit?

 

 

Against who? And for what?

 

A problem has been identified, and is being fixed.

 

 

 

 

Are you being serious? Against Intel for a bug which cannot be fixed without a performance hit. 

 

Would you be so cavalier if you bought a car for 50K 2 weeks ago, and the manufacturer said they discovered a bug that couldn't be fixed properly, but as a work around it would stop the car reaching 100KM/h? To make it worse, they couldn't tell you yet how much slower you would be allowed to go, but the potential range was a max speed of 66KM/h through to 92KM/h?

 

Nope, I didn't think so.

 

 

I don't know if the fix will slow the car down in normal day to day driving.
I only evidence I've seen so far suggest if the section of road has an incline of 12 deg, the air temp is 25, I have 3 passengers, and my elbow resting on the door,  there may be a noticeable slow down.

 

Plus is the bug with the car or the road surface or how we drive it.

 

Until there is more information, don't know who to sue or what for.

 

 

Wouldn't the analogy be "your car has 200hp, but due to these concerns we are going to limit it now to 132 - 184hp we can't tell you which"

Since updating the Windows 7 DEV VM I started getting the Font errors as posted in the previous reply.

 

Got fed up last night and upgraded the VM to Windows 10. I didn't do it before because I have a couple of applications that failed under Windows 8 during tests but hey, database management is more important...

 

Surprisingly those same applications worked with no problems on Windows 10. The only exception is that I am not able to do remote connections to IIS. No big deal, can use another Windows Server for this.

 

Update took about 45 minutes. The irritating thing is, as usual, Windows 10 installing all those crappy games. If you're running Windows 7 Pro and upgrade to Windows 10 you'd expect not to have those installed. Never mind. 

 

Font error now is gone. Another Windows 7 machine gone from this world.

If you brake rapidly when road conditions require a rapid turn the credit card you left on the dash will fly out the window and directly into the hands of a random stranger you didn't notice standing on the corner. See the woman in the red dress?

So we are saying, don't patch my car and potentially drop the HP to 132 - 184hp from 200hp as I will risk my credit cards being flung out of my car into the hands of a random stranger that I didn't notice standing on the corner, who happens to be an international cyber criminal, rather than an honest person. How far does this rabbit hole go?

You have a choice to make. Do you want the red pill or the blue pill?

Just installed a new BIOS/firmware to my HP EliteBook and it seems all good now - at least on this laptop. Wife's Folio is older so might have to wait a bit longer.

Any particular reason why remote IIS connections are not working?

I start IIS Admin and when I click on the Geekzone server a dialog shows a message saying it can't be done from this client.

 

Worked before on Windows 7. No big deal as I have a monitoring server that I can use for this - I rather not work directly on the IIS/SQL servers when possible.

I guess the outcome may be a slightly improved change management process then :)

A great tool to determine if your system is vulnerable, options available and if performance is likely to be affected: GRC InSpectre.
